Strategic Win for SIMPEC in NSW Infrastructure
WestStar Industrial Limited’s wholly owned subsidiary SIMPEC has secured a noteworthy contract valued at approximately $8 million to supply and install ventilation systems for the Western Harbour Tunnel project in New South Wales. This contract, awarded by ACCIONA on behalf of the NSW Government, represents a significant step in SIMPEC’s strategic push to deepen its footprint on Australia’s east coast infrastructure market.
The Western Harbour Tunnel is a major transport infrastructure initiative designed to alleviate congestion around Sydney’s central business district by providing a western bypass. By easing pressure on key corridors such as the Sydney Harbour Bridge and the Anzac Bridge, the project aims to improve traffic flow and safety for commuters, while integrating road and public transport networks more effectively.
Scope and Significance of the Contract
SIMPEC’s role involves the mechanical installation of two ventilation systems critical to the tunnel’s operation. These systems will manage airflow within the tunnel once it opens to traffic, ensuring safety and compliance with environmental standards. The work is scheduled to begin immediately and is expected to be completed by mid-2026, aligning with the broader project timeline.
Mark Dimasi, Managing Director of SIMPEC, highlighted the contract as a milestone that reinforces the company’s strategic direction in infrastructure. The collaboration with ACCIONA and Transport NSW not only underscores SIMPEC’s growing reputation but also positions it as a key player in delivering essential components of Australia’s national infrastructure.
Broader Implications for WestStar and the Infrastructure Sector
For WestStar Industrial, this contract award is more than just a revenue boost; it signals a successful expansion into the competitive NSW infrastructure market. The project complements WestStar’s diversified industrial services portfolio, which spans energy, resources, utilities, and infrastructure sectors. It also demonstrates the company’s ability to secure and deliver complex mechanical installation projects in partnership with major contractors.
As infrastructure development continues to be a national priority, contracts like this one could pave the way for further opportunities. SIMPEC’s expertise in structural mechanical and piping, electrical and instrumentation, and civil services positions it well to capitalize on upcoming projects across Australia.
Bottom Line?
SIMPEC’s Western Harbour Tunnel contract cements its east coast presence, setting the stage for future infrastructure wins.
Questions in the middle?
- Will SIMPEC secure additional contracts in NSW’s expanding infrastructure pipeline?
- How will project execution risks be managed to meet the mid-2026 completion target?
